In order to reduce how frequently the IMS is hit from the service, the service caches the azure-mgmt clients between API calls. While the management APIs should have some amount of authentication expiration redundancy built in, not all of them do.
This is seen with `ClientAuthenticationError`, most often with the nested exception record of `ExpiredAuthenticationToken`.
This wraps all of the compute layer functionality with a wrapper that checks if there has been an exception, and retries the request.

The primary "legacy" libraries are [azure-graphrbac](https://pypi.org/project/azure-graphrbac/) and azure-cosmosdb-table. The former has not been updated to use azure-identity yet. The later is being rewritten as [azure-data-tables](https://pypi.org/project/azure-data-tables/), but is still in early beta.
Add support for sharding across multiple storage accounts for blob containers used for corpus management.
Things to note:
1. Additional storage accounts must be in the same resource group, support the "blob" endpoint, and have the tag `storage_type` with the value `corpus`. A utility is provided (`src/utils/add-corpus-storage-accounts`), which adds storage accounts.
2. If any secondary storage accounts exist, they are used by default for containers.
3. Storage account names are cached in memory the Azure Function instance forever. Upon adding new storage accounts, the app needs to be restarted to pick up the new accounts.
We need to move to supporting data sharding.
One of the steps towards that is stop passing around `account_id`, rather we need to specify the type of storage we need.
